“#FBF with my little brother and sweet Luke. Joey, you’re so awesome and I’m so proud to be your big sis. Also, I’ve left you like 5 voicemails could you call me back? @the_penny_got_speed,” Nikki wrote on Instagram on the same day with a pic, which you can check out below!

The day before, Nikki was seen taking her two pet pooches out for a walk in L.A.

FYI: Nikki is carrying a Max Mara bag and a Lifefactory water bottle at the gym and her Dana Rebecca Designs necklace. She’s also wearing a Stella & Dot crossbody bag.
